A List Apart

I tought pre-parsing (scanner) was only active when DOM construction was paused while reading a blocking JS, and was not a mandatory step ie. there would be no pre-parsing at all if there is no blocking JS to load. Edge (and all other browers?) are pre-parsing the full page to collect images (and JS?) urls and add it to the loading list by (which?) priority. Did I understand correctly?
